Pulsar TCF-10B, System Manual, Page: 63 / 249

5.1 Preliminary Checks
5.1.1 Checking the Chassis
Nameplate
Verify that the proper dc supply voltage and
module options are on the chassis nameplate.
Also, check for narrow, wide, or extra wide band;
Phase Comparison or Directional Comparison (2-
or 3-Frequency).
Check to ensure that all required modules are
supplied and are installed in the proper chassis
slots. The slots are labeled on the top edge of the
chassis.
5.1.2 Inspecting for the Correct dc
Voltage
With the power “OFF,” remove the Power Supply
module and inspect it for the correct dc voltage, as
specified in Table 5-1.
5.2 TCF–10B Preliminary
Connections
1. Refer to the Block Diagram (see Chapter 7,
Signal Path) for keying and output connec-
tions.
2. Connect the dc supply to the appropriate
terminals on the Rear Panel (see Figures 3-1
and 3-4, in Chapter 3, Installation).
3. Terminate the Transmitter output with a non-
inductive 50 ohm, 25 W resistor.
4. Connect the Selective Level Meter (Rycom
6021A) across the 50 ohm resistor load.
You may perform the TCF–10B acceptance tests at your installation to determine that the TCF–10B is
operational. (See Test Equipment in Chapter 4, and Signal Path in Chapter 7.)
If the TCF–10B is a Transmitter (only) set, perform the following segments: 5.1, 5.2, 5.3, and 5.4. If the
TCF–10B is a Receiver (only) set, perform segments 5.1, 5.2, 5.5, and 5.6. If the TCF–10B is a Transceiver
set, perform segments 5.1, 5.2, and 5.7.

CAUTION
ALWAYS TURN “OFF” DC POWER WHENEVER
REMOVING OR INSTALLING MODULES.
NOTE
Perform Steps 3 and 4 only if the chassis
contains a transmitter.
